Problem with my '87 C-4



Problem with my '87 C-4

Postby sahlfeld » July 1st, 2011, 4:04 pm

I am getting no signal to my fuel pump, or fuel pump relay nor the fuel pump fuse.
I have checked my wiring from the ECM to the fuel pump relay and it is good. Where would the power supply come from to the ECM and on to the fuel pump relay.
I also have no signal at the 3amp fuse for inst lights.
Is there a common I should be looking for?
Thanks
Tony
